I have a question about the fillings used in many of the supplements that we eat, life extensionists or not. One of the most common filling material is soybean oil. What I am wondering is whether this poses any danger for human fertility. Phytoestrogens from the soybean have been implicated in such matters and are suspected of messing up both the male and female reproductive systems (for men they can lower the quality and quantity of sperm). My question is if there is a real danger for people that eat a lot of supplememtns. Does soybean oil contain phytoestrogens? Is soybean oil perhaps cleaned from other chemicals and thus safe in this respect? Are the amounts enough, aggregated over several formulations simultaneously consumed, to lower male fertility or mess up a womans hormonal cycle? I think these questions are important for all of us that eat many supplements, especially given the fact that the fertility of modern westerners is steadily declining.
Yes, it is a concern, but the amount is supplements is very low, and you can bite into one to see if it tastes fresh or rancid. The bigger problem is using these kinds of highly unsaturated oil for cooking, as well as what the supplements are. There are a lot of supplements that are not good for you. Many have anti-nutritional qualities. Fish/flax is asking for major free radical damage to your body. Trace amounts of things that many people eat a lot of is usually tolerable. However, I buy pure powder supplements, such as magnesium citrate, so that this is not a problem. I get most of my supplements through iherb.com
